Abstract
The present invention is directed to solid state organic light emitting devices and to methods for triplet excitation scavenging in such devices. More particularly, the present invention relates to a method for substantially reducing a triplet population in a solid state organic material, the method comprising providing molecules exhibiting non-vertical triplet energy transfer in the solid state organic material or at a distance smaller than a triplet exciton diffusion length from the solid state organic material.
